And, according to frontman Rob Halford, the band have a few other surprises up their sleeves – and he’s been delving into Priest’s back catalogue in preparation of something “very special” in 2020.

The Metal God tells Rolling Stone: “I’ve been feverishly working over the last few weeks and months with our stage designers to make something very, very special.

“We’re going to go deep, deep, deep into the catalogue and try to find songs that we’ve never played before and wrap it up into the history of Priest and the 50th anniversary.

“The official Priest 50th spectacular starts next year, so it’s going to be a great show. We’ve got some really big surprises and it’s going to be a wonderful celebration of Priest and British heavy metal.”

In August last year, Halford confirmed that Judas Priest were putting the pieces in place to mark the “incredible milestone” this year.
